Typical values for theoretical maximum specific gravity range from approximately 2.400 to 2.700 depending on the aggregate specific gravity and asphalt binder content. Unusually light or heavy aggregates may result in a value outside this typical range.

The terms specific gravity and density used in this test method are in accordance with Definitions 1. Density, as determined by this test method-the mass of a cubic meter of the material at 25°C. 2. Residual pressure, as employed by this test method-the pressure in a vacuum vessel when vacuum is applied.

The normal target in-place density on a “dense” hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result.

samples per lot. The average in-place mat density and joint density for a lot are determined and compared with Table 1 to calculate a single pay factor per lot based on in-place density, as described below. First, a pay factor for both mat density and joint density are determined from Table 1.

Home / Asphalt / Asphalt Maximum Theory Density Meter ... APPLICATION It is suitable to determine the theoretical maximum specific gravity of bituminous mixtures by vacuum process. It is used to design the ratio of bituminous mixtures, survey the road condition or calculate the void ratio and compactness of road construction. ...

To determine the weight of material multiply the volume by the density of material Weight = Volume × Density Using the previous example and assuming an asphalt pavement mixture density of 145 pounds per cubic foot (pcf) and a thickness of 4" we would perform the following calculations.

asphalt cement absorbed by the aggregate is also computed by the use of theoretical maximum specific gravity is determined by ASTM D2041. Although, this is one of the most critical test parameters in the design of HMA mixtures, its
